[ACCURATE AND FAST INFLATION]: Built-in premium brass components ensure powerful airflow speeds of up to 25L per minute, with a maximum pressure of 150 PSI, achieving full inflation in 3-5 minutes, relative to the size of the item being inflated. [SHARP LCD DISPLAY & BRIGHT LED LIGHT]: Backlit LCD digital display allows you to easily read the pressure. Regardless of the time of day or weather conditions, you can comfortably read and set the pressure with 4 units of measurement (PSI, BAR, KPA and KG/CM). The powerful LED lights will illuminate your field of vision at night, whether youre filling your tire or looking for something you misplaced. [EASY TO USE]: 1) Start your engine and plug the device into your 12V cigarette lighter socket or other 12V outlet. 2) Connect the air hose securely to the tire valve. 3) Set the pressure and power to inflate. Organize the hose and power cord within the back of your inflator, once complete. [AUTO-OFF FUNCTION]: Preset the pressure to your desired value and your pump will automatically shut off once that level is attained. This will ensure the tire is neither over nor under inflated.
